It is believed that in these explosions star cores collapse to neutron stars or black holes while outer stellar layers are ejected into cosmic void, creating spectacular expanding shells. With modern telescopes a supernova is discovered pretty much every day. Some of supernovae remnants (these expanding shells) were connected &hellip; Continue reading \"\"","thumbnail_url":"https:\/\/startrackworks.camk.edu.pl\/wp-content\/uploads\/2021\/01\/press1-724x1024.jpg"}
